Numerical Analysis of Geogrid CFG Pile-Supported Embankment on Soft Soil
This paper presents an optimum design and analysis of CFG pile-supported embankment for the national highway in India. Cement flyash and gravel piles are new approach of ground improvement column technology for the India. These techniques were used in china in many projects as highway and railway embankment for ground improvement. A couple two different dimension embankments 2D FEM model are used in this paper over the expansive soil near Surat City, Gujrat. The present study does with this observation by employing CFG pile support embankment composite foundation and screening its reflection through 2D FEM analyses. The present study on CFG pile variable length affects the slenderness ratio, material properties (Grade) as well as effects of area replacement ratio. The slenderness ratios of pile and thickness of sand layer on the proportion of loads are shared by CFG piles and its settlement response of composite foundation on different levels of vertical load by highway embankment. Results showed the thickness of sand mattress on CFG pile was transmission load effectively as significant thickness of it. CFG pile was efficiently in improving the bearing capacity and reducing vertical settlement of expansive soft soil. Other way results showed that incremental lengths of CFG pile reducing the settlements of composite foundation and increment in diameter of CFG pile effectively improved in bearing capacity of composite foundation. CFG pile material friction angle improves the bearing capacity of foundation system.
